You might need them for other reasons than why your teeth look. Bite problems, and other issues in your jaw that might need to be corrected.
I had braces for nearly two years. Head and neck gear apparatuses for four previous years(mostly that long b/c I didn't wear them when I needed to)
Braces are hard to deal with at times. They look weird, they often feel uncomfortable, and it's hard to deal with these things when you're a teen. Many of us who have had them know how that feels too.
But you will get through it. You've got most of it behind you already. I think you'll find when they do come off, your teeth will look just fine and will probably be healthier and more insured of a long, healthy life. And it's probably better for your jaw bones too.
And if you get a retainer, remember to wear it when they tell you too. I learned that one the hard way, so I'll pass that information along.
